. >> syria said yesterday's attack, there has been worse over the years but cutting off all diplomatic relations is extraordinary rare in peacetime. perhaps it was to teach a lesson to a country that doesn't play by the rules. a country which seems close to having a nuclear bomb. >> the iranians are being informed now we require the immediate closer of the iranian embassy in london and all iranian diplomatic staff must leave the united kingdom within 48 hours. if any country makes it impossible for us to operate on their soil, they cannot expect to have a functioning embassy here. >> so by the weekend, iran's embassy here in london, just like britain's embassy in tehran will effectively be closed down. almost at the very last moment, iran's foreign ministry put out a statement seeming to apologize for yesterday's attack, but it was too late and the apology wasn't strong enough. in six years, then, britain has gone from offering friendship to iran, that was angrily rejected, to shutting down all direct links altogether. and the basic reason is the political in fighting in tehran itself.
